PACKAGING MACHINE.

Application filed March 31, 192'1. Serial No. 457,375.A

My invention relates to a wrapped 'pacle of sticky fruit, such as raisins,

and a machine for automatically wrapping the same. This invention is an improvement 4over the machine shown and described in my pending' application, Serial` No. 119,682, liled Septf12, 1.916 which Yhasmatured into Patent No'. 1,389,669. It is required that the raisins be weighed or measured and put into uniform packages as rapidly and automatically as possible. It is also desired that the raisins beso wrapped before. being put into the cartons that the ends will be covered with a continuous portion of the wrapper, thus avoiding the folded ends which make it possible for a. person to straighten out the folded ends of the wrapper, after opening the end of the carton, and pick out the raisins and then refold the package, without tearing the wrapper. In my present method of wrapping the mat-ter, the bottom, sides and ends of the wrapped package are all covered by a continuous portion of `the .vrapper, and there is no folded end which can be opened, even after the end of the carton has been opened up, and in order to get at the raisins, they must be taken. out of the carton and unwrapped, or the wrapper over the exposed end must be torn.

l have illustrated my improved package and the various steps in its formation on the accon'ipanying sheet of drawings, and I have also shown one practical machine for automatically forming and wrapping the package. l will now describe the invention as .illustrated Figure 1 is a side elevation of a machine embodying my invention; Figure 2 is a top plan view thereof; Figure 3 is a side elevation of said ma.- chine from the opposite side to that shown in Fig. 1.

Referring now more in detail to the drawings, I will describe one practical embodiment Of my invention, or one means for 4automatically forming the wrapped package involving my invention. shown yis of general rectangular form, with abase, `1and theframe members, 2, 2, .in which the operating mechanism is mounted. Iwill `first describe the mechanism in detail, commencin atk the place where the power is applied, an will afterwards describe the use and operation of the machine from the reception ofthe terial to be wrapped to the discharge of the wrapped package.. y y v A main driving pulley, 3, is mounted on the outer end 'of a shaft, 4, provided with a clutch mechanism, 5,'comprisinga pinion, 6, having on its side the clutch teeth 7, and loosely mounted on said shaft 4. Y Also mounted ,on said shaft 4E, is a companion clutch member, 8, on the sleeve`9, adapted to be moved into and out of meshvwith the clutch teeth 7, and4 to this end said sleeve 9 said shaft, by means driving engagement with the clutch member The machine here Y wrapping paperand the mai 10, and is normally moved into 7, by means of a spring 11, on sai-d shaft, 4, as clearly shown in Figs. 12 and 13. The feather can be seen in Fig. 1. The clutch sleeve 9 is supported in a bearing member, 12, held in place thereon by means of a nut 13. Said bearing member 12 is provided at its side with a guide sleeve, 14, slidably mounted on a shaft, 15, having bearings in the frame members 2, 2, as indicated in Fig. 4. Mounted on the opposite side of the bearing member 12, is a plunger-like member 16, normally held in extended position by'means of a spring 17, within the plunger casing, 18, formed as a part of the bearing member 12. Said plunger member is provided with a notch, 16 in one side, within which is adapted to seat a trip lever, v19, which is normally drawn toward said plunger by means of -a coiled spring 20, attached at its opposite end to a fined pin `21. The plunger 1:6 is 'provided with a rounded corner, as at 16a,a'nd is adapted to be engage-d 'bya'fi'xed cam block, 22, mounted uponthe inner face of -a large gear, 23, whereby as said cam block 22 engages said plunger 16, it'forces said plunger, together with said bearing member 12, and the clutch sleeve, 9, away from the clutch pinion 6, thus disengaging the clutch teeth 7 and 8. Inasmuch as the clutch sleeve 9, is slidably secured to the shaft 4, by means of the feather, 10, it will be evident that when saidl parts are moved away from the pinion 6, and out of mesh with therclutch teeth 7, as above stated, said pinion 6, and

the large gear 23, will stand idle, the shaft 4, turning within said pinion 6, and the clutch sleeve 9, turning within the bearing member 12. The plunger 16, in the meantime will restupon the cam block 22, on the large gear 23, in its stopped position, thus holding the clutch sleeve 9, and the clutch teeth 8, thereof, out of driving engagement with the clutch teeth 7 on'said lpinion 6. Therefore, when the trip lever 19, is moved outwardly, in a manner yhereinafter described, out of the notch 16', inthe plunger 16, it allows the bearing member 12, and the 'clutch sleeve"9,*to be moved inwardly into driving engagement with the clutch teeth 7, by means of the spring 11, 'whereupon said pinion 6, being again locked to the shaft 4, drives the largegear 23, moving the'cam block on its inner face from under the plunger 16. Said plunger is again thrust outwardly in its normal position by its spring t 17, and the machine. continues to run until the gear 23 has made one complete revolution and the main cam block "22 thereon has again engagedv said plunger'ilo, and aga-in moved the bearingmember-12,`and the clutch 8, outof drivingengagement with theclutch teeth 7, of the pinion 6.

Thus-it will fbe lseen that the constantly driven shaft 4, is intermittently, 'by .Ineanslaof this clutch imechanisinA just rdeser-ihedthrwn `pivoted at 45,

into and out of driving engagement with the principal operating mechanism of the machine, said connection being from the clutch pinion 6, to the gear 23, on a shaft 24.

Mounted in the main frame is a bearing 25, Figs. 1 and 5, in which is a vertical shaft provided at its opposite ends with two beveled gears, 26 and 27. rhe upper gear 26, meshes with another beveled gear, 28, on a shaft, 29, provided with paper feeding rings,

'30. which contact with corresponding rings,

31, on a shaft, 32, adjustably mounted above the'shaft 29, and held inplace by means of set screws, 33.

The lower'bevel'ed gear 27 meshes with a large beveled gear, 34, on the shaft 24, which is drivenby the large gear 23, as seen in Figs2 and 5. Thus when said gear 23 is driven one "revolution,'said beveled gear 34 is vdriven'one revolution, driving gears 27, 26,'and 23, and feeding a sheet of wrapping paper, P,forwardly in position to receive the 'matter to be wrapped, as hereinafter iagainfreferred to. This paper can be fed from any suitable position, from a roll, through Aguide rollers, as and 36, Fig. 1. The opposite ends ofthe feed shafts 29 and 32, are provided with intermeshing gears, 37 and 38, as shown in Fig. 5, whereby the upper shaft 32 is driven from the lower shaft 29.

Mounted on the main shaft 24, next to' the large beveled gear 34, is a cam member, 39, Figs. 1, 4 and 5, for operating a lever, 40, pivoted at 41, and provided. with a cam engaging'froller, 42, and also connected with the lower end of a vertical rod, 43,`the upper end of which is connected with a knife, 44, and adapted to be moved downwardly to out the wrapping paper fed thereunder to the place of receiving the matter to'be wrapped. rfhus said knife is intermittently operated as said cam 39 is revolved with the shaft 24.

vAlso mounted on said shaft 24, at the other side of the beveled gear 34, is a larger disc cam 46, having the cam portion 46', which operates a cam lever, 47 pivotally connected to the frame vat 43, and provided with a cam roller y49. Saidlever is connected `to the lower end of a vertical rod, 50, the upper end of which is connected to a lever, 51, ona shaft, 52, provided with a lever, 53, for a purpose hereinafter referred On the other end of said shaft 24, referring to Figs. 3, 5 and 14, is an internal, intermittent gear, 54, having an external cam, 54', and internal gear teeth, 54a, clearly shown inl Fig. 14. Also mounted on said shaft, 24, within said internal gear, 54, and

turning therewith, is an external, intermittent gear, 55, between which gears 54'and 55, is an intermittent pinion, 56, mounted on a shaft,'57,-in the .traina-as seen 'in Fig. 5.

two shafts, 70

Anected to a spring, 'as

Said intermittent pinion, 56, intermittently operates said shaft, 57, alternately, first in one direction and then in the opposite direction through1 the actions of intermittent gears, 54 and 55. On said shaft 57, is a gear, 58, in mesh with a rack, 59, on the underside of a plunger, 60, indicatedin Fig. 3, which plunger by being reciprocated endwise operates to push the wrapped package from the wrapping pocket and into the receiving boX, 61, which has `an operating lever, 62, and is pivotally mount-ed at 68, whereby it can be turned to discharge the wrapped package. The end of said plunger, 60, forms one end wall of the wrapping pocket. By means of the internal, external and pinion gears, 54, 55 and 56, said plunger is intermittently moved outwardly to discharge a package and is then moved back'to its normal position, as will be better understood from the description of the use and operation of the machine later. The form of the wrapping pocket E best seen insection, F ig. 6, where the pocket is designated, P. The cam 54 on the exterior periphery of the internal gear 54, engages a cam lever, 64, pivoted at 65,"and having an arm 66, the upper end of which connects with a cross arm 67, the opposite ends of which connect with two crank arms, 68 and 69, on the outer ends of and 71, which shafts are provided near their opposite ends, near the middle of the machine, as seen inFig. 5, with fingers, 72 and 73, which connect, respectively, with sliding folding members, 74 and 75. to move them inwardly and then outwardly, in the folding operation, as again referred to. Said folding members work above the path of the plunger, in the pocket, P, Figs. 5 and 6, and move together to press the paper edges inwardly on top of the maferial being wrapped, as will be understood from reference to Fig. 9.

Mounted on said shaft 24, in the middle of the machine and at a space apart, are two cam discs, .76 and 77, provided on their faces, respectively, with cam blocks, 76 and T7, of different lengths', as will be understood by reference to Figs. 5, 15 and 17. These cam blocks engage cam levers, 78 and respectively, on shafts, 80 and 81, mounted in the inside of the frame members, 2, 2, as indicated in 3 and 5. On the outer ends of ,said shafts, 80 and 81, Fig. 5, are mounted rocker arms, 82 and 83, respectively, one end of each of which being con- 84, 85, and the other ends of which are connected with vertical rods. and 87, connected at their upper ends to the crank arms, 88 and 89, on the ends of two shafts, 90 and 91. Referring to Fig. 6, said shafts 90 and 91, are provided with crank arms, 92 and 93, connected by means oflinks, 94 and A95, with two folding wings, 96 and 97. @n the shafts, 90 and 91,

wardly, slightly',

'is loaded.` The hopper segments, 98 and 99, sliding bearing memcam segments escape the end portions of the bearing blocks, 'as will be lclear in Fig. 6, whereupon the wing folding members are turned inwardly to fold the wrapper sides down on. the material successively, as indi cated in Figs. 1,0 and 11. The wing member 97 is first' folded quickly and lifted, as th, cam block, 77, Figs. 5 and 17,is short.v While the wing folding member 96 is folded downwardly andheld a longer period by its cam operating block, 76', Fig. 15, which is much longer. During its down period, the plunger operates yand pushes the wrapped `package out into a carton which has been placed in the receiving box, 61, to receive it. This n'iovement of the folding wings bodily inbefore they turn on their hinges insures a proper folding f the wrapper and avoids its catching in the hinge joints. i

On the outer end of the shaft 24, is a cam member, 102, Figx, which operates a cam lever, 103, pivoted at104, on a shaft which is-provided in the middle part of the malchine with an operating arm, 105, which connects with vand operates a vertical gate 1iieinber,106, which is moved up to close the outer end of the wrapping pocket, and is moved down at the proper time, to permit the plunger to push the-wrapped package out into the carton in the receiving box, 61. This gate member is seen in Fig. 6.

Iwill now describe the receiving and weighing hopper mechanism. Mounted across the top frame: members 2, 2, is a supporting shaft, 107, on which is pivotally mounted abalance fork or frame, 108, the free end or fork of which pivotally supports a receiving hopper, 109. Pivotally mounted on top of said frame, nearits middle, is a latch plate or member, 110, the free end of which projects to the right, Figs. 1 and 2, and the other end of which rests freely on the frame 108. A second shaft, 111, is mounted lacross the frame of the machine., and carries an arm, 112, one end of which underlies the latch plateA 110, and the other end of which is provided with -a weight, lill, adjustable thereon, for the purpose of weigh ing a desired vquantity of material to be wrapped, as hereinafter again referred to.

Said hopper is provided on its opposite rsides with two open sleeves 114, 114, adapted to pass down over two guide pins, 115, 115, as shown, Figs. 1 and `8, the upper ends of vsaid pins being small enough not to interfere withlth'e free movement of the hopper as it 1s shown 1n detail in lio ' Fig. y7, and comprises a long box-like member, 109, having the bearings 169at at its op posite sides and by means of which it is pivotally supported by the fork or frame member,108. On its opposite sides it also has extensions 109b for the purpose of pressing the wrapping paper outwardly as said hopper moves down into the wrapping pocket, as hereinafter described. Two floor doors, 116, 116 are mounted in said hopper, intermediate itsends, as' shown in Fig. 7, said doors being provided with forks, 116% outside of the hopper and positioned to be engaged by cam pins, 117, 117, positioned to engage and move said doors open and closed as said hopper moves up and down, as will. be understood from the drawings. The mate ter to 'be wrapped is discharged into the hopper in any desired manner, until the proper amount 'for a package has been discharged thereinto,

rhe mechanism for tripping the clutch mechanism, hereinbefore described, is shown on Fig. 1, and comprises an arm, 118, on a shaft 119, -provided on its outer end with another arm 120, connected by means of a rod 121, to a bell crank, 122, the lower end of which is positioned, when moved, to move the trip arm 19, on the clutch mechanism, as clearly shown in Fig. 1. llhen the hopper with its load moves downwardly, ythe frame or fork 108 strikes the end of the arm, 116, which results in tripping the clutch and starting the machinery for one revolution, as before described.

T he use and operation of my invention as here illustrated, may be describedV as follows Assuming that the wrapping paper, l?, has been moved forwardly so as `to overlie the wrapping pocket, P', and this is done at the finish of each cycle of operation, and that the matter is being discharged into the receiving and weighing `hopper 109, when the correct amount has been placed in the hopper to overbalance the weight 113, which has been set to the desired position, the hopper moves down with its weight, the lower end nf the hopper pressing the paper down into the wrapping pocket below, with the result that the paper is formed substantially into the form shown in Fig. 8. At the finish of this downward movement, the projecting cam pins 117. at each side of the hopper, engage and move the forks, 1166, which opengthe doors, 116,` and discharges the material into the paper in the wrapping pocket, as in S. lThe extensions, 109b of the hopper, Fig. 7 have so pressed the folds of the paper that they remain infarpressed condition substantially as shown in Fig. 8, as the hopper is raised. The downward movement of the hopperhas tripped the clutch lever 19, as before described, andV the machine has started- The cam 46 on the 156, and thus operate wrapper, as shownv in vbe picked out without tea-ring cam disc 46, Fig. 1, has engaged and moved the arm 47, and through its connections has moved the arm 53 downwardly until it engages and moves the arm 108 on the shaft 167. which carries the hopper frame, which raises the hopper to its natural or receiving position, said hopper being held in its raised position by the engagement of the end of the arm 112 with the latch plate 110 which can tip in one direction to pass upwardly past the end of the arm 112 as the hopper arms 108 are raised to normal position. T he hopper is thus supported. As it descends with its weight, the latch moves off the end of the weight arm 112. The turning of the shaft 24, through the cam 54@ operates the levers 64,166, 67, and the shafts and 71, and thereby operates the end folding menibers together, designated 74 and 75, folding the end portions of the wrapper, as shown in Fig. 9. rthese are moved in and out. Following this action, the cam discs 76 and 77. operate the folding wings 97 and 96, successively, as before described, lirst folding over the right hand side of the wrapper, as shown in Fig. A10, and then following immediately the fold of the left hand side of the wrapper, shown in Fig. 11. lt will be understood that the matter, if it be raisins, is sticky, and as soon as the paper is pressed down on top, as shown, it sticksv in folded position. llhile the folding wing 96is vdown making the last fold, as in Fig. 11, the intermittent gears, 54, 55 and 56, operate the shaft, 57, and the largev gear the plunger, through its rack, 5?, pushing the wrapped package out into a carton which has been placed in the receiving box 61. ln the meantime, cam 102, Fig. 6, has operated through levers 103, 104, to withdraw the end gate 106, from the end of the wrapping pocket nearestthe receiving box 61, so that the plunger can push the package out. rlhese movements are all automatic and are properly timed, of course, so that they occur in proper sequence. thus making the operation automatic from the beginning. The beveled gear 46, through the beveled pinions, 27, 26 and 28, operates the paper feeding rollers, on shafts, 29 and 32, and the cam, 39, on the shaft 24, operates the knife 44, to cut the paper as it reaches the position above the wrapping pocket, as indicated in Fig. 4.

`Thus I have produced a new shown in Figs. V8 to 11, inclusive, automatically wrapped, and so wrapped that the bottom, sides, and ends, have continuous portions of the wrapper over them, with all the ends of the paper folded down on the top sideof tie matter. and the last fold of the wrapper covering these endsor edges of the 11. 1f the ends ofthe carton areonened, the raisins cannot the paper package,

Tapper, an object sought to be .accomplished in automatic wrapping machines of this character.
